25. Lithotrophy Modern and ancient lithotrophy among Archaea and Bacteria. Global appearance and distribution of inorganic energy- and electron sources: N-, S-, H-, C-, Mn- and Fe- compounds. Energetics of dissimilation reactions with inorganic electron donors. Coupling between chemolithotrophy and carbon assimilation. Prokaryotic versatility in creating membrane protentials by oxidizing inorganic electron donors. Coupling element cycles: a prerequisite for lithotrophy. Evolution of global biogeochemical cycles in the anoxic Precambrium and adaptation to oxic conditions.
